Amplifier Overload Check
Check that the amplifier is not overloaded by performing the following four steps:
1. Make sure that the extension speakers are connected to the audio output
transformer proper terminals (E1 through E7, and A1, A2).
2. While the music is playing, if the yellow CLIP LEDs on the amplifier stay OFF or
flicker in a random manner, the load is acceptable.
3. If a yellow CLIP LED is always lit or flickers continuously, the amplifier is overloaded
and will shut down, and you must perform Step 4.
If a red OVERLOAD LED on the amplifier flickers, the amplifier is overloaded and will
shut down. You must perform Step 4 below.
4. Do this step only if a CLIP or OVERLOAD LED came on as described in Step 3.
Find the source of the overload (shorted speaker wires, too many speakers
connected, or speaker power taps too high in total wattage). After you fix the short,
disconnect a few speakers or lower the speaker power tap selection to reduce the
wattage, then repeat Step 2.
